The carrier or suspension bars16, 17 correspond with each other but 1n service eX- ltend longitudinally in opposite directions, as. shown, and said bars are vpreferably of.

inverted channel shape in cross section and The bars 16, 17 have straight horizontal rinner end portions and thence said bars incline upwardly and outwardly below and to receive and direct the tension members 14 of the brake-beams, the outer ends of saidbars .16, 17 being detachably connected withl the outer ends of the safety guard bars 18, 19, by means of pins`20 whichextend through matching sleeve members formed on the adjacent ends vof the bars 16, 18 and bars 17, 19, as shown. The bars 16, 17 are substantially disclosed in my Letters Patent No. 1,519,762, dated December v16, 1924, and Letters'Patent No. 1,519,764, dated December 16, '1924.

The safety guard bars 18,19 correspond with each other butin service extendlongitudinally in opposite directions', as shown, and said bars are preferably of inverted channel shape in cross section and present 'convex upper surfaces..y Thebars 18, 19 have straight horizontal inner end portions and thence said bars extend upwardly along the inner sidesof the side flanges of the spring plank and thence longitudinally above the brake-beams 11, 12 to the outer ends of the carrier or suspension bars 16, 17, to ywhich they are secured, as aforesaid. The safety guardbars 18,19 are substantially .disclosed in my` aforesaid Letters Patent, except that in said Letters Patent the said bars are vintegral with each other or constituteparts of ay single bar, whereas in thepresentiinstance saidbars 18, 19 are each in a separate piece and capable of independent adjustment and independent removal when necessary.

The means for securing theinner end portions of the bars16, 17 'to the spring plank 10, comprise a durable bracket 21 contain- Aing longitudinal channels 22, 23 forI the in ner endv portions of the respective bars 16, 17 and having -laterally extending flanges 24 to engage the bottom of the spring plank, a central upwardly pressed transverse strip 25 ywhich also engages. the spring plank'and at its ends affords abutments, when necessary, for the inner ends of the bars 16, 17, longitudinal shoulders or seats 26 for the 'depending side edges of the Vbars 16, 17 and longitudinalelevated seats 27 for the concave'lower surfacesofthe bars 16, 17. The

brackets 21 are secured to Vthe spring plank v10 by meansfofirivets 28 which extend vertically through. saidy plank and through the .flanges 24 of said brackets. "Atitsendseach j Y j .vertical flanges 38 .to closely receive the y bracket 21is flangeddownwardly, asl at 29.

'The formation .of the bracket 21 is one which results in the production of a bracket` of great strength and efliciency. The bracket-channels 22,V 23 are open at their outer ends and said channels closely receive the inner end portions of the carrier or sus pension bars 16, 17, which while. firmly litting the channels may be forced into and from said channels and also be adjusted longtudinally therein, as occasion may require. One feature of the present invention resides in the fact that each carrier or suspension bar, with its guard bar, may be adjusted longitudinally to meet the requirements of the brake-beam and especially the position ofthe truss-rod thereof. In Figs. 1 and 2 the carrier bars, with their respective guard bars, are shown as having been adjusted out wardly to correctly position the inclined surfaces of the carrier bars at a suitable height to meet'th@ position Vof the truss rods. The position of brake-beams varies somewhat with the condition of the pivoted brakehangers and other 'causes and the inclined surfaces of the carrier bars should have a definite relation to the truss rodsl of the beams in their small variations of position, andv henceV I provide for the longitudinal adjustment of said bars. If the carrier bars and guard bars should not in the position shown in Figs. 1 and 2, meet the requirements of the truss rods of a' different set of brake-beams, said lbarswould Vbe adjusted inwardly to bring a more elevated portion of the-inclined surface of the carrier bars below the truss rods. By having the guard bars 18, 19 in independent parts 'as distinguished from being integral with each other, the carrier bars 16, 17 may be adjusted longitudinally in the manner just explained.

When the carrier bars requirev noV adjustment with relation to the 'truss rods, the inner ends of said bars will abut against the opposite edges of the abutment strip 25, this 'guard bars against. the upper surface of the spring plank 10 comprise two parallel longitudinally extending .angle bars 80, 31, two

transverse locking pins 32, 33, a bridge piece 34 upon the upper surfaces of adjacent portions of the guard bars andv crossing the joint between said portions and, preferably,

a lock 35 for securing said pins 32, 33

against accidentall loss 'in the event ofthe breakage or loss of the cotter keys A36 with j which said pins are equipped.

.. The angl@J bars 30, 31 have their flanges '3.7 seated upon the spring plank 10 and eX- tended transversely in opposite directions so as to leave a clear space between their width of and house the inner end .portions of the guard bars 18, 19. The angle bars 30,

ceiving,- the inner end portions of the carrier bars and clamping means atl the upper side of the spring plank releasably securing the inner end portions of said lguard bars thereto, said cai'rier bars, with their respective guard bars, being longitudinally adjustable for the purpose of meeting the mounting of the brake-beam.
